Your 100 cap is fine, it simply means that you can't overheat the engine as much as you could with a higher pressure cap. If you have a leak in your system (cracked tank top or whatever), the lower pressure cap is better. Mercedes tended to increase cap pressure in later models: my 123 has a 120 cap while my 124 and 210 both have 140 caps.
So, I should go ahead and order the proper cap too? It sounds like from what I have been reading now that it should be the 120.

Cool..... Literally! I guess now is better than 1 or 2 months from now when it is REALLY HOT and it rains every afternoon! I hope it goes well for you. I always get paranoid ordering anything this fragile. It seems like fins always get bent or corners get dinged. Maybe we will get lucky.

I still cannot find that fat little short hose beneath the thermostat housing. It looks pretty bad too. I guess I will wait until I have the rad out, then take it in and size it up for replacement.
